At 40k miles, i've been noticing the symptoms of a dying mech unit (bang/jerk to stop, shifting from drive to reverse), etc. Those symptoms happened when i pull up from stationary, put the car in reverse. Car will also throw transmission error code on dashboard and put in "limp mode" from time to time. Since it was out of warranty, audi quoted me $5800 to replace the entire mechatronic unit. Many threads on the audi forum confirm the issue was due to quality control on audi's part, and audi refused to issue a callback or pay for the expense for out-of-warranty cars with faluty 7-speed dsg transmission.
Experienced turbocharger failure when coming to a stop after getting off the interstate after approximate 2. 5 hours of driving. Engine died as car slowed down so suspect the turbos failed while driving but ram air from interstate speeds was adequate to maintain the engine until it slowed down. The extended run time with failed turbos resulted in metal fragments in the oil so after inspection, the engine was replaced under an extended warranty with a used engine. This engine has approximately 58k miles on it and i think the replacement engine had 11k or so on it. This occurred on dec 26th, 2019. This past february, 2021, noted an odd whistle sound from the turbo but no warning lights and slightly sluggish acceleration. The following day it seemed to run fine on my way to work but on the way back it ran rough and then died so i had to steer off the road into a parking lot as i lost power steering. Further investigation determined that one turbocharger had completely failed (the turbine wheel was completely sheered off) and the other had excessive play in the shaft. The 75k factory maintenance had just been performed in decker, 2020, as had the 65k maintenance earlier in the year. Since the replacement engine was no longer covered under a used parts warranty or my extended warranty, the cost of turbo replacement was entirely out of pocket. I also had to pay for some extra work on the first engine replacement due to discovery of extra work required for the swap that wasn't in the initial quote to the extended warranty company.
Turbo failure. First start up of the day, vehicle would cut off and die. Took it to the audi dealer and it was diagnose with turbo failure.
At 74000 miles, the turbochargers failed. I was in traffic on a busy thoroughfare and engine quit working. Could not drive, or turn car. I was stopped.. Thankfully police came quickly. This a known problem with this model car that audi is aware of.
As i was pulling off the interstate to use the restroom, my engine lost all power. I lost control of power steering and power brakes while in motion. I was able to come to a complete stop at the stop sign. I was able to restart the car temporarily and enough to pull into the gas station right off the interstate. I did not think there was anything wrong and went to use the bathroom. When i came back outside to the car it would not start. I had to use my insurance company roadside assistance to have the car towed to an audi dealership. The audi service department informed me that i had a turbo failure. There was scorching present when the sr tech viewed the turbo with a borescope. The car is known for this issue and hasn't been recalled. There are 2 tsbs that are related to turbo failure for these cars, tsb2044640/9. Thank goodness i had an extended warranty. I will have 2 new turbos, a new oil screen and pcv due to this issue and that is a 5 figure cost.
When driving in town the car abruptly stopped running, steering and brakes failed. Caused by both turbochargers going out at the same time. 36,000 miles a few months out of warranty. Apparently this is known issue with the audi's and audi has not issued a recall or anything according to the audi dealer. $11,000 repair. Very scary when power lost and remained off.
Both turbochargers failed due to oil starvation at just over 45000 miles. This happened while driving and required the vehicle to be transported directly to the dealer as a major failure.
Accelerated from a stop to about 20 mph, when it went into 2nd gear the engine revved and skipped into 3rd gear. Warning stated "transmission malfunction. No reverse gear. You can continue driving. " reverse no longer works. Engine revs to 5000 rpm when driving 20-25 mph.
Biturbo failure caused engine to turn off without warning at highway speeds. No power. I had to merge through two lanes to the shoulder without power. Car would not restart. I was told by the dealer that this is a known problem and that some have been on fire. Need to replace the turbo. Internet says at least $14,000. 00, though i am covered under warranty.
